Electroretinogram (ERG) flicker photometry was used to study the spectral mechanisms in the retinas of white-tailed deer (Odocoileus virginianus) and fallow deer (Dama dama). In addition to having a rod pigment with maximum sensitivity (lambda max) of about 497 nm, both species appear to have two classes of photopic receptors. They share in common a short-wavelength-sensitive cone mechanism having lambda max in the region of 450-460 nm. Each also has a cone having peak sensitivity in the middle wavelengths, but these differ slightly for the two species. In white-tailed deer the lambda max of this cone is about 537 nm; for the fallow deer the average lambda max value for this mechanism was 542 nm. Deer resemble other ungulates and many other types of mammal in having two classes of cone pigment and, thus, the requisite retinal basis for dichromatic color vision.
视网膜电图(ERG)闪烁光度法被用于研究白尾鹿(弗吉尼亚鹿)和黇鹿视网膜中的光谱机制。除了拥有一种最大敏感度(λmax)约为497纳米的视杆色素外,这两个物种似乎都有两类明视觉感受器。它们共有一种短波敏感视锥机制,其λmax在450 - 460纳米范围内。每个物种还有一个在中波具有峰值敏感度的视锥,但这两个物种的该视锥稍有不同。在白尾鹿中,这个视锥的λmax约为537纳米;对于黇鹿,该机制的平均λmax值为542纳米。鹿与其他有蹄类动物以及许多其他类型的哺乳动物一样,拥有两类视锥色素,因此具备双色视觉所需的视网膜基础。
